How to tell whether you are talking or playing a recording?

The way to tell whether you are talking or playing a recording is as follows:

1, the sound quality is different. The sound made by the real voice has a strong "personality". When we listen to a person, we know who he is, but a fake voice is different from a real voice.

2, the scope is different. The true voice range is not wide, the range is around g-f2, and there are no inflection areas and inflection points. The sound above g2 becomes falsetto, with obvious inflection marks, but falsetto overtones are few, so the sound in the mid-bass area is not strong enough.

3. Different vocal skills. If all the vocal cords vibrate when you sing, then you are singing with a real voice. If the vocal cords vibrate when singing, it is singing in falsetto.

Recording is the process of recording sound signals on a medium. The process of reproducing sound from a signal recorded on a medium is called playback. The two processes of recording and playing are collectively called recording and playing. Common ones are record playing, tape playing and CD playing. As far as recording and playback systems are concerned, there are mono and stereo recording and playback systems.
